General
Performance Characteristics
The table below gives the general operating characteristics of the 2701C. Resolution refers to the minimum adjustment that may be made in the selected range. Max Current refers to the maximum amount of current that may be supplied by the selected range without affecting its accuracy (4-wire mode must be used). Wideband Noise refers to the maximum amount of microprocessor and power supply noise (from 10Hz to 10kHz) that may be present on the output voltage. The Linearity of the 2701C is defined as the maximum allowable deviation from a straight line between the zero and full-scale outputs on each range. Output Impedance refers to the impedance of the voltage amplifier.

Option LNF
Specifications
The Model 2701C is available
with a modification that reduces the Wideband noise. This
modification is designed as Option "LNF". A 2701C
equipped with Option LNF has a maximum output voltage of
± 40 volts. The following Wideband Noise
specifications apply to instruments equipped with Option
LNF only.
